Um, it's a pretty normal thing, as a man, wouldn't you naturally feel some connection to someone you have children with?
I dunno if maybe you're driving at why not do the kid/family thing, but never get married. This way, every 5 yrs., you can get someone else younger, and repeat, maybe 5X in your life? Anthony Quinn did that--I think he had a 50 y.o. kid, and a newborn. So is that better?
There are dumb questions, not dumb people. This was a dumb question.
